ABSTRACT

Objective To explore the characteristics of blood uric acid levels and its correlation with calcium and phosphorus levels, and glucose and lipid metabolism in obese adolescents in weight-loss training camps. Methods In this study, 357 obese adolescents aged 12-18 were selected as the research subjects, and 135 normal-weight adolescents were selected as the controls. The body shape and blood uric acid characteristics of the subjects were measured and analyzed. Further, 59 subjects were selected from the obese adolescents for blood calcium, blood phosphorus and glucose and lipid metabolism index tests to analyze the correlation between blood uric acid level and calcium, phosphorus, and glucose and lipid metabolism indicators. Results The average blood uric acid level of obese adolescents was (527.12±122.94)μmol/L, (566.58±122.51)μmol/L for boys, and (468.35±97.79)μmol/L for girls. The blood uric acid level of the obesity group was significantly higher than that of the control group (P<0.001 for boys, P<0.05 for girls), and it was higher in boys than in girls (P<0.01). Obese adolescents with high uric acid accounted for 73.39%. The HOMA-IR of obese adolescents was 5.79±3.04. The blood uric acid level was significantly correlated with blood calcium, total cholesterol, and low-density lipoprotein cholesterol (P<0.05). Gender and low-density lipoprotein cholesterol were the main influencing factors of blood uric acid (P<0.05). Conclusion Obese adolescents have high blood uric acid levels, low calcium and high phosphorus in the body, and a higher incidence of insulin resistance. There exists a positive correlation between the blood uric acid level and the body's calcium and phosphorus metabolism and glucose and lipid metabolism in obese adolescents. Clinical monitoring of lipid metabolism indicators such as low-density lipoprotein has certain reference value for the prevention and treatment of hyperuricemia.

ABSTRACT

Objective:To explore the mediating effect of attentional bias of negative information between fatalism and death anxiety in lung neoplasms patients.Methods:This study was a cross-sectional study. It was convenient to select 312 lung neoplasms patients treated in the Department of Oncology, First Affiliated Hospital and Second Affiliated Hospital of Air Force Military Medical University the Chinese People′s Liberation Army, from April 2021 to April 2022 as the research subjects. Questionnaires were conducted with Fatalism Scale, Attention to Negative Information Scale, and Templer′s Death Anxiety Scale. Structural equation model were constructed based on self-regulatory executive function models.Results:The total score of fatalism, attentional bias of negative information, and death anxiety of 312 lung neoplasms patients were (61.68 ± 11.92) points, (39.57 ± 5.19) points, and (61.23 ± 9.30) points, respectively. Attentional bias of negative information was significantly positively correlated with fatalism ( r = 0.594, P<0.01). Death anxiety was significantly positively correlated with fatalism and attentional bias of negative information ( r = 0.494, 0.558, both P<0.01). Attentional bias of negative information played a partial mediating role between fatalism and death anxiety, and the mediating effect accounted for 37.7% of the total effect. The value of each fitness index of the mediation effect model was within the acceptable range. Conclusions:Attentional bias of negative information is an intermediary variable between fatalism and death anxiety of lung neoplasms patients. Nursing staff should pay attention to the level of attentional bias of negative information of lung neoplasms patients and carry out targeted nursing interventions from the emotional processing process to reduce the level of death anxiety in patients with lung neoplasms.

ABSTRACT

Objective:To investigate the correlation between lung ultrasound score at the end of spontaneous breathing trial (SBT) and cumulative fluid balance at 48 h and their predictive value of extubation outcome in patients with intro-abdominal infection (IAI) under mechanical ventilation.Methods:A retrospective study was conducted. Patients with IAI under mechanical ventilation for more than 48 h were collected from three hospitals from October 1, 2017 to September 30, 2018. Routine demographic variables and clinical characteristics were recorded. The patients were divided into the successful extubation group and failed extubation group according to whether they could maintain spontaneous breathing for 48 h after extubation. LUS at the end of SBT (before extubation) and cumulative fluid balance at 48 h were compared between the two groups. LUS and cumulative fluid balance at 48 h were analyzed by bivariate correlation analysis, and their correlations with shallow fast breathing index (RSBI) and precursor protein of BNP (Pro-BNP) were analyzed. The predictive value of LUS at the end of SBT (before extubation) and cumulative fluid balance for extubation failure were analyzed by receiver operating characteristic curve (ROC).Results:Totally 207 patients were enrolled. There were significant differences in LUS before extubation [12 (10, 14) vs. 16 (14, 17) points], cumulative fluid balance [-318 (-1 116, 200) mL vs. 1 140 (685, 1 614) mL], RSBI [60 (55, 66) (times/min)/L vs. 70 (65, 78) (times/min)/L], pro-BNP [250 (122, 1 292) pg/mL vs. 1156 (285, 4 346) pg/mL], IAP >15 mmHg [32.8% vs. 46.6%], and ICU stay [8 (6, 12) days vs. 11 (8, 14) days] ( P<0.05). Logistic regression analysis showed that the COPD history, RSBI, LUS at the end of SBT, and cumulative fluid balance at 48 h before extubation were independent risk factors for extubation failure. Correlation analysis showed that LUS was moderately correlated with cumulative fluid balance at 48 h ( r=0.41, P<0.001), weakly correlated with RSBI ( r=0.381, P<0.001), and weakly correlated with pro-BNP ( r=0.220, P<0.001). Cumulative fluid balance at 48 h was weakly correlated with RSBI ( r=0.31, P<0.001), but not with pro-BNP. LUS at the end of SBT and cumulative liquid balance at 48 h had predictive value for extubation failure [AUC=0.87 (95% CI: 0.82-0.91), AUC=0.89 (95% CI: 0.85-0.94), P<0.001]. Conclusions:There is a moderate correlation between LUS at the end of SBT (before extubation) and 48 h cumulative fluid balance in patients with IAI and mechanical ventilation. LUS at the end of SBT (before extubation) and cumulative fluid balance at 48 h have some predictive value for extubation failure.

ABSTRACT

OBJECTIVE@#To develop and validate a mechanical power (MP)-oriented nomogram prediction model of weaning failure in mechanically ventilated patients.@*METHODS@#Patients who underwent invasive mechanical ventilation (IMV) for more than 24 hours and were weaned using a T-tube ventilation strategy were collected from the Medical Information Mart for Intensive Care-IV v1.0 (MIMIC-IV v1.0) database. Demographic information and comorbidities, respiratory mechanics parameters 4 hours before the first spontaneous breathing trial (SBT), laboratory parameters preceding the SBT, vital signs and blood gas analysis during SBT, length of intensive care unit (ICU) stay and IMV duration were collected and all eligible patients were enrolled into the model group. Lasso method was used to screen the risk factors affecting weaning outcomes, which were included in the multivariate Logistic regression analysis. R software was used to construct the nomogram prediction model and build the dynamic web page nomogram. The discrimination and accuracy of the nomogram were assessed by receiver operator characteristic curve (ROC curve) and calibration curves, and the clinical validity was assessed by decision curve analysis (DCA). The data of patients undergoing mechanical ventilation hospitalized in ICU of the First People's Hospital of Lianyungang City and the Second People's Hospital of Lianyungang City from November 2021 to October 2022 were prospectively collected to externally validate the model.@*RESULTS@#A total of 3 695 mechanically ventilated patients were included in the model group, and the weaning failure rate was 38.5% (1 421/3 695). Lasso regression analysis finally screened out six variables, including positive end-expiratory pressure (PEEP), MP, dynamic lung compliance (Cdyn), inspired oxygen concentration (FiO2), length of ICU stay and IMV duration, with coefficients of 0.144, 0.047, -0.032, 0.027, 0.090 and 0.098, respectively. Logistic regression analysis showed that the six variables were all independent risk factors for predicting weaning failure risk [odds ratio (OR) and 95% confidence interval (95%CI) were 1.155 (1.111-1.200), 1.048 (1.031-1.066), 0.968 (0.963-0.974), 1.028 (1.017-1.038), 1.095 (1.076-1.113), and 1.103 (1.070-1.137), all P < 0.01]. The MP-oriented nomogram prediction model of weaning failure in mechanically ventilated patients showed accurate discrimination both in the model group and external validation group, with area under the ROC curve (AUC) and 95%CI of 0.832 (0.819-0.845) and 0.879 (0.833-0.925), respectively. Furthermore, its predictive accuracy was significantly higher than that of individual indicators such as MP, Cdyn, and PEEP. Calibration curves showed good correlation between predicted and observed outcomes. DCA indicated that the nomogram model had high net benefits, and was clinically beneficial.@*CONCLUSIONS@#The MP-oriented nomogram prediction model of weaning failure accurately predicts the risk of weaning failure in mechanical ventilation patients and provides valuable information for clinicians making decisions on weaning.

ABSTRACT

The systemic inflammatory response caused by various pathogenic factors is a key stage in the development of acute respiratory distress syndrome (ARDS). At present, suppression of the inflammatory response and symptomatic support are main methods for the treatment of ARDS. Alveolar epithelial autophagy has an important role in the regulation of the inflammatory response in ARDS. Autophagy is a normal immune mechanism in the body, and it is a metabolic process by which phagocytes degrade intracellular components with the help of lysosomes to maintain intracellular homeostasis. Current studies have shown that pathogenic factors both inside and outside the lung can cause alveolar epithelial cells to form an unfavorable internal environment of hypoxia, starvation, infection, and even apoptosis by triggering inflammatory responses, leading to autophagy dysfunction. Excessive autophagy activation can continue to aggravate inflammatory responses. Autophagy related proteins such as Beclin1, microtubule-associated protein 1 light chain 3 (LC3), mammalian target of rapamycin (mTOR), and p62 are common autophagic markers in current research, which play a crucial role in regulating the autophagic process and the development of lung injury. Therefore, the expression of cellular autophagy genes can be used as early markers and important mechanisms of lung injury in septic ARDS. The Hippo signaling pathway is derived from the protein kinase Hippo in Drosophila, and the Hippo and autophagy are two conserved pathways that are essential for the protection of homeostasis in vivo. The mutual regulation of Hippo signaling pathway and autophagy is currently a hot topic in the academic community. This paper reviews the relevant literature to explore whether the Hippo signaling pathway can regulate cellular autophagy to alleviate the inflammatory response in septic ARDS, so as to provide further research directions for the treatment of ARDS.

ABSTRACT

ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with cognitive behavioral therapy (CBT) in the treatment of impulse control disorders in patients with Wilson's disease (WD, syndrome of combined phlegm and stasis). MethodA prospective study was conducted on 90 WD patients with the syndrome of combined phlegm and stasis and impulse control disorders (ICD) treated in the Department of Encephalopathy of the First Affiliated Hospital of Anhui University of Chinese Medicine from August 2018 to February 2023. They were randomized into a control group, a CBT group, and a treatment group, with 30 patients in each group. The control group received routine Western medicine treatment (basic copper removal). The CBT group received cognitive behavioral therapy in addition to the therapy in the control group, and the treatment group received Gandouling decoction in addition to the therapy in the CBT group. Each course of treatment was 8 days, and the patients were treated for 4 courses. Before and after treatment, the 24-hour urine copper (24 h U-Cu), non-ceruloplasmin-bound copper (NCC), traditional Chinese medicine (TCM) syndrome score, unified WD rating scale part Ⅲ (UWDRS Ⅲ) score, Barratt Impulse Scale Version 11 (BIS-11) score, Buss-Perry aggression questionnaire (BPAQ) score, modified overt aggression scale (MOAS) score, and treatment emergent symptom scale (TESS) score of three groups of patients were determined and statistically analyzed. ResultBefore treatment, there was no statistically significant difference in the level of 24 h U-Cu or NCC among the three groups. After treatment, all the three groups showed an increase in 24 h U-Cu (P<0.01) and a decrease in the NCC level (P<0.05, P<0.01). There was no significant difference in the 24 h U-Cu level among the three groups after treatment. After treatment, the NCC level showed no significant difference between the control group and the CBT group, while the NCC level in the treatment group was lower than that in the control group and CBT group (P<0.05). Before treatment, there was no statistically significant difference in the TCM syndrome score among the three groups. After treatment, the TCM syndrome scores of all the three groups decreased (P<0.01). Moreover, the treatment group had lower TCM syndrome score than the control group and CBT group (P<0.05). Before treatment, the UWDRS Ⅲ, BIS-11, BPAQ, and MOAS scores had no statistically significant differences among the three groups. After treatment, the UWDRS Ⅲ, BIS-11, BPAQ, and MOAS in all the three groups declined (P<0.05). Moreover, the CBT group and treatment group had lower UWDRS Ⅲ, BIS-11, BPAQ, and MOAS scores than the control group (P<0.05), and the treatment group had lower BIS-11 and BPAQ scores than the CBT group (P<0.05). ConclusionThe combination of Gandouling decoction and CBT can ameliorate impulse control disorders in the WD patients with combined phlegm and stasis.

ABSTRACT

Esophageal cancer is the most common malignant tumor in the digestive system in China. Because of the hidden clinical symptoms, the disease has reached the local advanced stage once discovered. For patients who have lost the opportunity of surgery, synchronous chemoradiotherapy is recommended, however, the recurrence rate after chemoradiotherapy is still high. Chemotherapy, radiotherapy and surgery are commonly used for recurrent patients, but the survival rate of recurrent patients after treatment is not satisfying. In recent years, immunotherapy has been successfully applied in various solid tumors, and its efficacy and safety in the treatment of advanced and recurrent metastatic esophageal cancer have also been recognized in the field of esophageal cancer. This article aims to provide high efficacy and low toxicity treatment methods for patients with recurrent esophageal cancer after chemoradiotherapy through summarizing the relevant literatures of various treatments including immunotherapy.

ABSTRACT

To investigate the effect of long-term indwelling gastric tube on the prevention and treatment of esophageal stenosis after endoscopic submucosal dissection (ESD) for esophageal circumferential superficial cancer, data of patients with esophageal circumferential superficial cancer who underwent ESD in the First Affiliated Hospital of Nanjing Medical University from January 2018 to December 2021 were retrospectively analyzed. There were 15 patients with gastric tube placement (GTP) after ESD (the GTP group ), and 23 patients without GTP (the non-GTP group). The general information, lesion location, pathological stage, postoperative complications, degree of esophageal stenosis (water intake), pain conditions, number of hospitalizations and medical expenses were compared between the two groups. The results showed that there was no significant difference in age, gender, lesion location or postoperative pathological stage between the two groups ( P>0.05). Compared with the non-GTP group, the rate of water intake in the GTP group was significantly higher (11/15 VS 6/23, P<0.05), the frequency of pain was less in the GTP group (7.3±3.1 times VS 10.7±3.6 times, t=3.00, P<0.05), and the number of hospitalizations and the medical expenses after ESD to before and after stent placement were significantly lower in the GTP group than those in the non-GTP group ( P<0.05). There were no significant differences in the incidence of delayed bleeding and perforation, or time of the first stenosis after ESD between the two groups ( P>0.05). The results of the study initially showed that long-term indwelling gastric tube after ESD can reduce the degree of esophageal stenosis with good safety for esophageal circumferential superficial lesions.

ABSTRACT

Objective:To explore the diagnostic value of mechanical power (MP) in patients with moderate to severe acute respiratory distress syndrome (ARDS) based on the Medical Information Mart for Intensive Care-Ⅲv1.4 (MIMIC-Ⅲ v1.4).Methods:The information of ARDS patients undergoing invasive mechanical ventilation for no less than 48 hours who were hospitalized at Beth Israel Deaconess Medical Center in Boston, Massachusetts from June 2001 to October 2012 in the MIMIC-Ⅲ v1.4 were collected. The demographics of patients, disease severity scores, ARDS etiology, prognostic indicators, pre-ventilation arterial blood gas analysis and respiratory parameters within 48 hours of ventilation were extracted. According to the lowest oxygenation index (PaO 2/FiO 2) before ventilation, the patients were divided into mild to moderate ARDS group (> 150 mmHg, 1 mmHg≈0.133 kPa) and moderate to severe ARDS group (≤ 150 mmHg), and the differences in baseline characteristics between the two groups were compared. The independent predictors associated with the severity of ARDS were analyzed using Logistic regression. The receiver operator characteristic curve (ROC curve) was plotted. The area under ROC curve (AUC) was calculated to evaluate the diagnostic value of MP for moderate to severe ARDS. The Youden index was used to determine the diagnostic threshold of MP for moderate to severe ARDS. According to the cut-off value of MP based on Youden index, all ARDS patients were divided into high and low MP groups. Kaplan-Meier survival curve was used to analyze the 28-day survival status of patients. Results:A total of 403 ARDS patients were enrolled in the study, including 107 subjects with mild to moderate ARDS and 296 with moderate to severe ARDS. There were significant differences in age, sequential organ failure assessment (SOFA) score, the lowest PaO 2/FiO 2 before ventilation, the last PaO 2/FiO 2 before ventilation, 28-day mortality, the length of intensive care unit (ICU) stay, duration of mechanical ventilation, lung dynamic compliance (Cdyn) in the second 24 hours of ventilation and positive end-expiratory pressure (PEEP), plateau pressure (Pplat), driving pressure (ΔP), respiratory rate (RR), lung static compliance (Cst), MP, inspired fraction of oxygen (FiO 2) within 48 hours of ventilation between the two groups. After adjusting variables such as age, SOFA score, the last PaO 2/FiO 2 before ventilation, and related respiratory mechanics parameters, multivariate Logistic regression analysis showed that higher ΔP, PEEP and MP, and lower last PaO 2/FiO 2 before ventilation were independently associated with moderate to severe ARDS [odds ratio ( OR) and 95% confidence interval (95% CI) was 1.137 (1.032-1.252), 1.333 (1.139-1.561), 1.102 (1.030-1.179), and 0.996 (0.993-0.998), respectively, all P < 0.01]. The ROC curve analysis showed that the best cut-off value of MP for the diagnosis of moderate to severe ARDS was 18.1 J/min with sensitivity of 81.42% and specificity of 60.75%, and the AUC was 0.745 (95% CI was 0.690-0.799). According to the cut-off value of MP obtained by ROC curve, all ARDS patients were divided into high MP group (> 18.1 J/min) and low MP group (≤ 18.1 J/min). The Kaplan-Meier survival curve showed that the 28-day cumulative survival rate in the high MP group was significantly lower than that in the low MP group (73.8% vs. 85.1%; Log-Rank test: χ2 = 5.660, P = 0.017). Conclusion:MP is an independent predictor of the severity of ARDS, and it can be used to diagnose moderate to severe ARDS.

ABSTRACT

Objective:To analyze the differentially expressed gene (DEG) in rats with sepsis-induced exogenous acute respiratory distress syndrome (ARDS) and explore the early diagnosis and protective mechanism of sepsis-induced ARDS at the transcriptome level.Methods:Twelve 6 to 8 weeks old male Sprague-Dawley (SD) rats were randomly divided into lipopolysaccharide (LPS) induced sepsis-induced ARDS model group (model group, intraperitoneal injection of LPS 15 mg/kg) and control group (intraperitoneal injection of the same volume of normal saline), with 6 rats in each group. RNA was extracted from the left lung tissue of the two groups, and the paired-end sequencing mode of the illumina Hiseq sequencing platform was used for high-throughput sequencing. The DESeq2 software was used to screen DEG with | log 2 (fold change, FC) | ≥ 3 and P < 0.001. Gene ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed on DEG. STRING and CytoScape software were used to construct a protein-protein interaction (PPI) network and screen key genes. The peripheral blood mononuclear cell (PBMC) of 20 septic patients admitted to the emergency and critical care medical department of Lianyungang First People's Hospital from March to November 2021 and 20 age-matched healthy people in the same period were isolated and extracted, and the key genes were verified by real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). Results:A total of 286 DEG were screened, including 202 up-regulated genes and 84 down-regulated genes. GO enrichment analysis showed that DEG was mainly involved in biological processes such as neutrophil chemotaxis migration, antibacterial humoral response, host immune response, and humoral immune response. KEGG analysis showed that DEG mainly played a biological role through interleukin-17 (IL-17) signaling pathway, tumor necrosis factor (TNF) signaling pathway, and chemokine signaling pathway. In PPI analysis, a total of 262 node proteins were screened, and the interaction relationship was 852 edges. The first 15 key genes were IL-6, TNF, IL-10, IL-1β, chemokine ligand 1 (CXCL1), CXCL10, chemokine receptor 3 (CXCR3), CXCR2, CXCL9, chemokine ligand 7 (CCL7), CXCL11, CCL1, CXCL13, CCL12, and CCL22. Five representative key genes were performed on PBMC of blood samples from septic ARDS patients and healthy controls by RT-qPCR. The results showed that their expression was significantly higher than that in the healthy controls [IL-6 mRNA (2 -ΔΔCt): 2.803±1.081 vs. 0.951±0.359, TNF mRNA (2 -ΔΔCt): 2.376±0.799 vs. 1.150±0.504, CXCL10 mRNA (2 -ΔΔCt): 2.500±0.815 vs. 1.107±0.515, CXCR3 mRNA (2 -ΔΔCt): 1.655±0.628 vs. 0.720±0.388, CCL22 mRNA (2 -ΔΔCt): 1.804±0.878 vs. 1.010±0.850, all P < 0.05], and the trends were consistent with the RNA-Seq results. Conclusion:Biological processes such as chemotactic migration and degranulation of inflammatory cells, cytokine immune response, and signal pathways such as CXCL10/CXCR3 and IL-17 play important roles in the occurrence and development of sepsis-related exogenous ARDS, which would provide new ideas and targets for further study of lung injury mechanisms and clinical prevention and treatment.

ABSTRACT

Objective:To explore the diagnosis process and treatment experience of severe coronavirus disease 2019 (COVID-19) patients with heparin resistance (HR).Methods:The medical team of the First People's Hospital of Lianyungang admitted 2 severe COVID-19 patients with HR in intensive care unit (ICU) during their support to the designated hospital for the treatment of COVID-19 patients in Lianyungang City in November 2021. The clinical features, laboratory examinations, imaging features, treatment and prognosis of the two patients were analyzed.Results:Both severe COVID-19 patients received mechanical ventilation, 1 patient was treated with extracorporeal membrane oxygenation (ECMO) support. Both patients were complicated with lower extremity deep venous thrombosis and HR phenomenon under routine dose anticoagulant therapy. The maximum daily dose of unfractionated heparin exceeded 35 000 U (up to 43 200 U), the 2 patients failed to meet the standard of anticoagulation treatment, and the course of disease was prolonged. After that, argatroban was given 0.4 μg·kg -1·min -1 combined with anticoagulant therapy, the activated partial thromboplastin time (APTT) of patients undergoing ECMO could be maintained at 55-60 seconds and the activated coagulation time (ACT) of them could be maintained at 180-200 seconds. After ECMO support or later sequential mechanical ventilation, both patients recovered and were discharged, and deep venous thrombosis was also effectively controlled. Conclusion:HR phenomenon often occurs during the treatment of severe COVID-19 patients, the anticoagulation regimen should be adjusted in time, and the anticoagulation effect combined with argatroban is clear.

ABSTRACT

@#To investigate the effects and possible molecular mechanism of S-oxiracetam(S-ORC) on learning and memory impairment in mice, mice were divided into 5 groups, control group, model group, high-dose of S-ORC (0.96 g/kg), medium-dose of S-ORC (0.48 g/kg) and low-dose of S-ORC (0.24 g/kg) treatment groups.Step-down test and Y-maze test were used to investigate the effects of S-ORC on the brain.The results of step-down test revealed that the mice in high and medium-dose groups could significantly decrease the reaction time, fault times and prolong the incubation periods of memory compared with the model group.Compared with the model group, the fault times of mice in high and medium-dose groups decreased significantly and the right times to find the safety increased significantly in Y-maze test.Furthermore, through treatment with S-ORC (high and medium-dose groups), the content of Ach in mice brain was significantly higher than that in model group, and the level of AChE decreased significantly.The above results suggest that the underlying mechanism of S-ORC on learning and memory impairment in mice may include the amelioration of the central cholinergic nervous system.

@#To investigate the neuroprotective effect and possible molecular mechanism of PNU-282987 on rats subjected to ischemia and reperfusion. In this study, middle cerebral artery occlusion/reperfusion(MCAO/R)in rats was used as the animal model. The 44 Sprague-Dawley(SD)rats were divided into 4 groups, sham group, model group, low-dose of PNU-282987(1. 2 mg/kg)and high-dose of PNU-282987(2. 4 mg/kg)treatment group. Y-maze test was tested for the learning and memory abilities of rats, and we also examined the brain infarct size, brain edema and neurological dysfunction in rats. Furthermore, HE staining was used to evaluate the neuronal injury and TUNEL assay was used to evaluate the neuronal apoptosis in the rat brain. The results revealed that the learning and memory abilities of rats in treatment group improved significantly, and treatment with PNU-282987 reduced brain infarct size, lessoned brain edema, lessened neurological dysfunction, ameliorated pathological injury and prevented neuronal apoptosis. The above results suggest that the underlying mechanism of PNU-282987 on improving learning and memory abilities of rats after cerebral ischemia and reperfusion may include the inhibition of neuronal apoptosis.

ABSTRACT

Objective:To identify the clinical correlations between the cross-sectional area loss of the erector spinae muscle (ESMcsa Loss) and serum growth differentiation factor-15 (GDF-15) in mechanically ventilatied patients in ICU. In addition, to investigate their diagnostic value for ICU-acquired weakness (ICU-AW) and their predictive value for 60-day survival in mechanically ventilated patients.Methods:Ninety-two patients with acute respiratory failure, who required mechanical ventilation therapy, were randomly selected among hospitalized patients from June 2018 to November 2019. The serum GDF-15 level was detected by ELISA, the total cross-sectional area of the right and left erector spinae muscles was calculated by CT images, and the patient's muscle strength was assessed using the British Medical Research Council (MRC) muscle strength score on day 1 and day 7. The patients were divided into the ICU-AW group and the non-ICU-AW group according to the MRC-score on the 7th day of ICU admission. The correlations between plasma GDF-15 level, ESMcsa loss, and MRC score on day 7 were investigated. The receiver operating characteristic (ROC) curve was used to calculate the predictive value of serum GDF-15, ESMcsa loss, and ESMcsa loss ratio on day 7 of mechanically ventilated patients in the diagnosis of ICU acquired muscle weakness. Moreover, the predictive value of GDF-15 and ESMcsa loss ratio on the 90-day survival status of the patients was assessed using survival curves.Results:Ninety-two patients were enrolled. According to whether the MRC-score on the 7th day was less than 48, 49 cases were included in the ICU-AW group and 43 cases in the non-ICU-AW group. The mechanical ventilation time, length of ICU stay and length of hospital stay in the ICU-AW group were higher than those in the non-ICU-AW group, and there were no significant differences in other baseline indicators. There were no significant differences in serum GDF-15, ESMcsa and MRC-score between the two groups on day 1. The GDF-15 level in the ICU-AW group was significantly higher than that in the non-ICU-AW group while ESMcsa and MRC-score were significantly lower than those in the non-ICU-AW group on day 7 [GDF-15 (pg/mL): 2529.53±625.67 vs. 1614.21±567.18; ESMcsa (cm 2): 23.76±6.85 vs. 29.15±6.5; MRC-1score: 41.10±3.35 vs. 51.23±2.84; all P <0.001]. ESMcsa loss and ESMcsa loss ratio were significantly positively correlated with serum GDF-15 levels on day 7 ( r = 0.2355 and 0.3192, respectively). ESMcsa loss and ESMcsa loss ratio were significantly negatively correlated with MRC-score ( r = -0.3072 and -0.3527, respectively). The ROC curve analysis showed that plasma GDF-15 level, ESMcsa loss, and ESMcsa loss ratio on day 7 had predictive value for ICU-AW diagnosis in mechanically ventilated patients [Areas under the ROC curve (AUC) were 0.904, 0.835, and 0.889, all P <0.001]. The 60-day survival curve demonstrated that the survival rate was 60.0% in the high GDF-15 group, while was 77.8% in the low GDF-15 group; and was 60.0% in the high ESMcsa loss ratio group, while was 80.0% in the low ESMcsa loss ratio group (all P<0.05). Conclusions:There was a significant correlation between the cross-sectional area loss of the erector spinae muscle and the increase of serum GDF-15 level after 7 days of mechanical ventilation in ICU, suggesting the acute muscle wasting and skeletal muscle hypofunction, which has certain diagnostic value for ICU-AW, and can predict the 60-day survival status of mechanically ventilated patients in ICU.

ABSTRACT

Objective To investigate the value of mechanical power(MP)to predict the potential of the lung recruitment maneuver and assess prognoses in patients with acute respiratory distress syndrome(ARDS).Methods Patients with moderate-to-severe ARDS who required mechanical ventilation therapy longer than 24 hours were randomly selected April 2017 to April 2019.The lung recruitment maneuver(RM)protocol was performed according to the patient's condition,their MP,lung ultrasound score(LUS),oxygenation index(PIF),and dead volume ratio(Vd/Vt),which were monitored before the RM and one hour after the RM.The patients were divided into the lung recruitment maneuver potential positive group(RMP-P group)and lung recruitment maneuver potential negative group(RMP-N group)according to whether the variation in the patient's RM aeration score(ΔLUS)was ≥ 5.Differences in MP between the two groups were compared and correlations between MP variation(Δ MP),aeration score variation(Δ LUS),oxygenation index variation(Δ P/F),and dead volume ratio variation(Δ V d/Vt)were analyzed.The receiver operating characteristic curve(ROC)was used to calculate the predictive value of MP for the potential of RM and the prognosis(28-day mortality)of patients with moderate or severe ARDS.Results Eighty-three patients were enrolled in the study,45 in the RMP-P group and 38 in the RMP-N group.There was no statistical difference in the baseline levels between the two groups(P>0.05).After RM treatment,MP,LUS scores,and Vd/Vt for each patient in the two groups decreased significantly compared to the pre-RM values,whereas,the P/F increased significantly(P<0.05).The MP,LUS scores,and Vd/Vt in the RMP-P group were significantly lower than those in the RMP-N group(P<0.05),whereas there was no difference in the PIF between the two groups after RM treatment(P>0.05).The Δ MP,Δ LUS,and Δ V d/Vt in the RMP-P group were significantly higher than those in the RMP-N group(P<0.05).There was no difference in the Δ P/F between the two groups(P>0.05).There was a significant positive correlation between Δ MP and Δ LUS and Δ Vd/Vt in all patients(r=0.4746,0.3995,P<0.01)and no significant correlation with Δ P/F(r=0.0314,P>0.05).The area under the ROC curves of Δ MP for predicting the potential of RM was 0.856,with a sensitivity of 91.1%and a specificity of 63.2%.The AUC of the 28-day survival status was 0.788,with a sensitivity of 84.3%and a specificity of 62.5%(P<0.05).Conclusions Mechanical power monitoring before and after RM can be used to predict the potential of the lung recruitment maneuver and assess the prognosis in patients with moderate-to-severe ARDS.
